The movie itself copy the Seven and Silence of the Lambs formula, but with a far worst cast and an extremely low budget for the Fx's.
So, first acting is bad keeping in mind who the main characters are here. The only who make an OK job is John Malkovich. All the others are pretty bad here.
Second, the script is interesting till it become obvious. The Twist is Ok, but not credible. So, it's just a bit dissapointing.
Last, Fx's are the worst I've seen in a long time. It's soap Opera level. Looks like they couldn't even shot an action scene decently.
So, even all it's flaws, it is quite entertaining if your are looking for the new version of The Silence of the Dambs.
